Lesson 2: Electricity

Wrapping Up

Conclusion

What did you learn about electricity in your community? Review the different types of power plants and how they harness energy. Is your community doing anything to offer alternative sources of electricity?

Questions to Discuss

  • What are the ways energy is generated for use in homes and businesses? Explain how each one works. (Fossil fuels are heated and burned to produce steam that turns the blades of the turbine. Hydropower uses flowing water to spin the blades of the turbine. Nuclear power boils water, and the steam turns the turbine. Wind power uses the wind to turn the turbine blades. Solar panels convert the energy of the Sun directly into electricity without the use of turbines.)
  • How are fossil fuels formed? (Heat and pressure beneath the Earth's surface turn the buried remains of plants and animals into fossil fuels.)
  • What is the difference between renewable and nonrenewable energy? (Nonrenewable energy cannot be replaced, so they may run out one day; renewable energy resources are continually being produced.)

Things to Review

Review the different ways that electricity can be produced. Find time for your child to share what she learned on her field trip with the rest of the family.
